毒理性
识别和使用:对苯二甲酰亚胺二樟脑磺酸是一种固体。它被用作广谱UVA吸收剂,并具有一定的UVB吸收能力。它已经在动物中作为紫外线屏障进行了测试。人体研究:无数据可用。动物研究:在大鼠中进行的90天口服重复剂量研究中,在300 mg/kg/天的剂量下未发现与剂量相关的效果。在1,000 mg/kg/天的剂量下,雄性在第四周出现了磷质血症,雌性在第13周出现了蛋白质、白蛋白和球蛋白水平的降低。有证据表明,喂食对苯二甲酰亚胺二樟脑磺酸的雄性动物甲状腺重量有所变化,然而,由于对照组动物被发现甲状腺重量异常低,这一观察结果的有效性存在疑问。随后的21天研究使用三乙酰胺和钠盐对甲状腺代谢进行研究,在305 mg/kg和444 mg/kg的剂量下未发现与治疗相关的变化。
IDENTIFICATION AND USE: Terephthalylidene dicamphor sulfonic acid is a solid. It is used as broad spectrum UVA absorber with some UVB absorption. It has been tested as an ultraviolet screen in animals. HUMAN STUDIES: There are no data available. ANIMAL STUDIES: In a 90-day oral repeat dose study in rats, no dose related effects were found at 300 mg/kg/day. At 1,000 mg/kg/day there was phosphoremia in males at week 4 and decreased protein, albumin and globulin levels in females at week 13. There was some evidence of variation in thyroid weight in the male animals fed terephthalylidene dicamphor sulfonic acid, however, there was some doubt as to validity of this observation as the control animals were found to have unusually low thyroid weights. Follow up 21-day studies using the triethalanoamine and sodium salts on thyroid metabolism found no treatment related changes at dose rates of 305 mg/kg and 444 mg/kg respectively.
